In the online request form for Canvas sites, the next semester will be added to the form three weeks prior to the start of early registration for students. The opening date for early registration is listed in the Academic Calendar on the Office of the Registrar web site.
Instructors who need a Canvas site for a semester that is not listed should request a Development/Sandbox site. The Development/Sandbox option is always available in the Semester dropdown field on the form (See Fig.1).
